Computer Facial Animation
Computer facial animation is primarily an area of computer graphics that encapsulates methods and techniques for generating and animating images or models of a character face. The character can be a human, a humanoid, an animal, a legendary creature or character, etc. Due to its subject and output type, it is also related to many other scientific and artistic fields from psychology to traditional animation. The importance of human faces in verbal and non-verbal communication and advances in computer graphics hardware and software have caused considerable scientific, technological, and artistic interests in computer facial animation. Although development of computer graphics methods for facial animation started in the early-1970s, major achievements in this field are more recent and happened since the late 1980s. The body of work around computer facial animation can be divided into two main areas: techniques to generate animation data, and methods to apply such data to a charact ...

Computer Graphics
Computer graphics deals with generating images and art with the aid of computers. Computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by graphics hardware, computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as Computer-generated imagery, computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of Computer graphics (computer science), computer science research. Some topics in computer graphics include user interface design, Sprite (computer graphics), sprite graphics, raster graphics, Rendering (computer graph ...

Simulation
A simulation is an imitative representation of a process or system that could exist in the real world. In this broad sense, simulation can often be used interchangeably with model. Sometimes a clear distinction between the two terms is made, in which simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Another way to distinguish between the terms is to define simulation as experimentation with the help of a model. This definition includes time-independent simulations. Often, computer simulation, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paul Ekman
Paul Ekman (born February 15, 1934) is an American psychologist and professor emeritus at the University of California, San Francisco who is a pioneer in the study of emotions and their relation to facial expressions. He was ranked 59th out of the 100 most eminent psychologists of the twentieth century in 2002 by the ''Review of General Psychology''. His empirical and theoretical work helped to restart the study of emotion and non-verbal communication in the field of psychology, and introduced new quantitative frameworks which researchers could use to do so. He also carried out important early work on the physiology of emotions. Biography Childhood Paul Ekman was born in 1934 in Washington, D.C., and grew up in a Jewish family in New Jersey, Washington, Oregon, and California. His father was a pediatrician and his mother was an attorney. His sister, Joyce Steinhart, is a psychoanalytic psychologist who, before her retirement, practiced in New York City.

Carl-Herman Hjortsjö
Carl-Herman Hjortsjö (8 December 1914 – 3 July 1978), born Carl-Herman Hirschlaff, was a Swedish anatomist, physician, and physical anthropologist. His contributions to historical osteology were instrumental in establishing it as an academic field in Sweden. Hjortsjö was born in Malmö, Sweden, to Herold Hirschlaff, a practicing physician, and Ester Hirschlaff (née Sandstedt). He obtained his medical license in Lund, Sweden, in 1942. During his studies at Lund University's Department of Anatomy, Hjortsjö was taught by and Carl Magnus Fürst, two of Sweden's pioneering anatomists at the time. In 1945, Hjortsjö earned his Doctor of Medicine degree with a dissertation on the morphogenesis of epithelial pulmonary primordium—the development of the early lung tissue—in cats. In 1948, Hjortsjö made significant contributions to the study of human liver anatomy, becoming the first to demonstrate its segmental division. His findings later proved essential for advancements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facial Action Coding System
The Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö. It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978. Ekman, Friesen, and Joseph C. Hager published a significant update to FACS in 2002. Movements of individual facial muscles are encoded by the FACS from slight different instant changes in facial appearance. It has proven useful to psychologists and to animators. Background In 2009, a study was conducted to study spontaneous facial expressions in sighted and blind judo athletes. They discovered that many facial expressions are innate and not visually learned. Method Using the FACS human coders can manually code nearly any anatomically possible facial expression, deconstructing it into the specific "action units" (AU) and their temporal segments that produced the expression. As AUs are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fred Parke
Frederic Ira Parke is an American computer graphics researcher and academic. He did early work on animated computer renderings of human faces. Parke graduated from the University of Utah with a BS degree in physics in 1965. He was then a graduate student of the University of Utah College of Engineering where he received his MS (1972) and PhD (1974) in computer science. In 1972, in a project partially financed by DARPA, Parke made the first 3D animation of a representation of a human face, his wife's face. This animation used a wireframe geometry overlaid with Gouraud shading that produces approximate renderings of curved surfaces. The technique was invented by Parke's Utah colleague Henri Gouraud. A Computer Animated Face In 1974, he created a more complex, parametric model of a human face, demonstrating various expressions and speech synchronization. Snippets of this animation, along with Ed Catmull's 1972 animation of his left hand, were used in the 1976 film '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biology
Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, History of life, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell (biology), cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability (homeostasis). Biology examines life across multiple biological organisation, levels of organization, from molecules and cells to organisms, populations, and ecosystems. Subdisciplines include molecular biology, physiology, ecology, evolutionary biology, developmental biology, and systematics, among others. Each of these fields applies a range of methods to investigate biological phenomena, including scientific method, observation, ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English Natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint presentation with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical Schoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bulwer
John Bulwer (baptised 16 May 1606 – buried 16 October 1656) was an English people, English physician and early Baconian method, Baconian natural philosopher who wrote five works exploring the Body and human communication, particularly by gesture. He was the first person in England to propose educating deaf people, the plans for an Academy he outlines in ''Philocophus'' and ''The Dumbe mans academie''. Life John Bulwer was born in London in 1606 and continued to work and live in the city until his death in October 1656 when he was buried in St Giles in the Fields, Westminster. He was the only surviving son of an apothecary named Thomas Bulwer and Marie Evans of St. Albans. On her death in 1638 John Bulwer inherited some property in St Albans from which he derived a small income. Although information about his education is unclear, there is evidence that he was probably educated in Oxford as an unmatriculated student in the 1620s. His known friends had nearly all been educated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
